The early medieval Parish church of St. Martin Busskirch with its cemetery rests on the remains of a Roman building (1st to 4th century AD). It is one of the oldest churches around the Lake Zürich. Even the citizens of Rapperswil had to attend services in Busskirch until Count Rudolf II of Rapperswil built his own church and a chapel next to Rapperswil Castle in 1253.
In 1351 St. Martin Busskirch was incorporated by the monastery (until 1838). In co-operation with Jona the settlement formed an Allmendgenossenschaft (farmer's association), reigned by the Counts of Rapperswil, latter by the city of Rapperswil. In 1253 the parish churches of Rapperswil and Jona were established: St. Martin Busskirch lost its former importance and was in 1945 integrated in the Roman Catholic parish Rapperswil.
References:The Pilgrimage Church of Wies (Wieskirche) is an oval rococo church, designed in the late 1740s by Dominikus Zimmermann. It is located in the foothills of the Alps in the municipality of Steingaden.
The sanctuary of Wies is a pilgrimage church extraordinarily well-preserved in the beautiful setting of an Alpine valley, and is a perfect masterpiece of Rococo art and creative genius, as well as an exceptional testimony to a civilization that has disappeared.
The hamlet of Wies, in 1738, is said to have been the setting of a miracle in which tears were seen on a simple wooden figure of Christ mounted on a column that was no longer venerated by the Premonstratensian monks of the Abbey. A wooden chapel constructed in the fields housed the miraculous statue for some time. However, pilgrims from Germany, Austria, Bohemia, and even Italy became so numerous that the Abbot of the Premonstratensians of Steingaden decided to construct a splendid sanctuary.
